Bolivar Flats Shorebird Sanctuary in April 2008

United States, Texas


Located on the Upper Texas coast, northeast of Galveston, the Bolivar Peninsula is essentially a washover bar separating Galveston Bay to the north, from the Gulf of Mexico to the south. At the southern end is the Bolivar Flats Shorebird Sanctuary, 1,146 acres consisting of coastal beach with mudflats and this is the prime birding spot on the peninsula. The beach was extensively damaged by Hurricane Ike in Sept. 2008, but is recovering well. Other nearby spots on the tip of Bolivar Peninsula (all west of Retillon Rd) are also birdy, including French Town Road, Fort Travis Seashore park, ferry landing at tip of peninsula. Horseshoe Marsh and Munday Marsh Bird Sanctuaries are also nearby.

The Bolivar Peninsula is on the Great Texas Coastal Birding Trail, site nos. UTC 56-60. See External Links.1

Site Information

History and Use

In 1816 the Bolivar Peninsula was named for Simon Bolivar (1783-1830), the Venezuelan military and political leader.

The Bolivar Flats Shorebird Sanctuary was first established in the late 1980's, with the permission of Galveston County. The beach was closed to vehicles with the building of a vehicular barrier. Over the years more land was acquired and the sanctuary is now 1,146 acres in size. The Western Hemisphere Shorebird Reserve Network recognizes it as a site of hemispheric importance, and National Audubon Society and Birdlife International, as an Important Bird Area.

Areas of Interest

  • Every third Saturday a species count occurs at Bolivar Flats, sponsored by Houston Audubon, which is an excellent way for visitors to learn from local experts. It begins at 8am at the ferry landing.
  • During Spring migration (mid-March to mid-May) there are volunteers at Bolivar Flats, with spotting scopes, to help visitors with shorebird identification.
  • Horseshoe Marsh Bird Sanctuary
  • Rollover Pass

Access and Facilities

You can drive right up to the ocean's edge on the flats themselves but take care not to get stuck in the mud.


  • From Houston take I-45 South to Galveston. In town I-45 turns into Broadway. Follow Broadway to Seawall Boulevard. Turn left on Seawall. Turn left on Ferry Road to the terminal (ferry is free of charge). You will exit the ferry on Hwy. 87. Follow this for 3.7 miles to Retillon Road. Turn right and drive to the beach. Turn right on the beach and drive on the beach to the vehicular barricade where you may park.
  • From Fifth Street in High Island, turn left onto Hwy. 124. Go to the stop sign. Turn right on to Hwy. 87 and it is about 25 miles to Retillon Road. Turn left on Retillon and drive to the beach. Turn right on the beach and drive on the beach to the vehicular barricade where you may park.
  • Driving along the beach is free, but parking permits are required if you intend to park anywhere on the beach. To visit the shorebird sanctuary, you must park at the vehicular barrier and enter the sanctuary on foot. The permit fee is $10 a year and permits are available from most stores and real estate agents on the peninsula, or by contacting the Galveston County Parks Department in advance of your trip: Galveston County Parks Department, Tel: 409-934-8100.

bernerjc's review top spot on the Upper Texas Coast for shorebirds. free. Only downside is hard to get to from Galveston /Houston. Must take car ferry which is fast in winter but requires long waits in the spring/summer during middle of day
